On a stormy September night, a young man comes to Baker Street seeking Holmes’s help with a chain of unexplained events in his family. Letters from distant places have arrived with five orange pips inside. Before the fire, Holmes and Watson listen as the visitor traces the history of the warnings and the memories attached to them.

At the end of September, violent wind and rain cover London. Watson is staying at Baker Street while his wife visits her family, and he spends the evening with Holmes beside the fire. Then the bell rings. The two men look up from their books and records and listen for the unexpected visitor outside the room.

John’s account moves to the period when his father inherited the house. He recalls what they found in the attic that had once been kept locked, then brings the family history forward to the reason for his visit. Holmes and Watson listen for the connection between the old letters and the danger that now troubles him.

After the visitor leaves, Holmes and Watson remain in the room while the storm continues outside. They arrange the facts hidden in the family story: the places from which the letters came and the time between each warning and what followed. Their quiet discussion asks how far the available knowledge and records can carry the reasoning.

The next morning brings pale light to Baker Street. Holmes is preparing to begin his inquiries after the previous night’s consultation, while Watson sits at the breakfast table and asks about his plans. With coffee and the unopened morning newspaper before them, the two men begin to discuss the work that lies ahead.
